A carbon dioxide dry cleaning apparatus and system for the control thereof is disclosed. The apparatus comprises a wash vessel, a working vessel containing a carbon dioxide cleaning medium and operatively associated with the wash vessel, a pump operatively associated with the wash vessel, a condenser connected to the working vessel, a still operatively associated with the working vessel (which still may be a separate still or incorporated into other system components as explained below), a compressor operatively associated with the wash vessel, and a pressure release valve operatively associated with said working vessel. At least one filter is included in the system, but the filter and still may be consolidated together in a single vessel. The apparatus includes a suitable controller which, operating in association with appropriate valves in the apparatus, provides a system that is used to place the apparatus in a cleaning cycle for washing articles therein, a waking cycle separate from the cleaning cycle during which distillation, recharging and other maintenance and preparatory function can be performed, or a resting cycle or resting state for long term periods of idleness.
